Published at Chemical Engineering Science – Experimental screening of metal nitrides hydrolysis for green ammonia synthesis via solar thermochemical looping

Abstract: Ammonia is a fundamental chemical commodity for fertilizers and as a novel energy vector. Solar-driven ammonia synthesis is proposed as a sustainable alternative to the catalytic energy-intensive and CO2-emitting Haber-Bosch process. The considered thermochemical process aims to produce ammonia from nitrogen and water (N2 + 3H2O → 2NH3 + 1.5O2) via redox cycles using a solar heat source, thus bypassing …

Solar Energy Materials and Solar Cells – Incorporation of CaZrO3 into calcium-based heat carriers for efficient solar thermochemical energy storage

Abstract Calcium-based materials (CaCO3/CaO) have shown significant potential for use in thermochemical energy storage systems for concentrated solar power generation due to their low-cost, high-energy storage efficiency, and operational temperature range. However, the energy storage performance of calcium-based heat carriers degrades rapidly over cycles due to high-temperature sintering, limiting practical applications. In this study, we …
